Mences Changes...worried!!

Hi I am new to the site. I am 39 years old and I was diagnosed with PCOS when I was 22 years old. I hate this disease. It has caused a lot of problems for me. In the past year I have developed the worse PMS ever...I get sick all over .. a feeling I cannot describe. My emotional state 3 weeks out of the month is out of control mostly with fear, anxiety and paranoid. One good thing is that I have been getting a period for the last year since June of 07.... until july I missed completely. For the last 4 weeks I have been dizzy, lightheaded, fatigue, anxious, hot, shaky, depressed...but mostly fatigued. The past 10-12 days I could feel my breast get tender and bloating ...pms symptoms. So I figured I was getting my period. Well, sure enough I got it 4 weeks from when I was due in July. It started dark red like normal. I felt fine ok not great... (I usually feel bad the first 2 days I bleed) then by 10pm that night I was lightheaded and dizzy, my heart was racing and I really started to flow. The only thing that concerns me with these symptoms is that my blood is really bright red with very little texture and no clots. Usually, I have brown to start then dark red to brighter red with mucus like flow and clots. It kind of freaked me out... almost like regular blood. I got it thursday night...I barely slept and worked yesterday with heavy flow from thursday night. I felt like was going to pass out all day. The bleeding has slowed down since last evening but It is still the same color and texture. But I am so tired and still little lightheaded. I am not pregnant and I have had some back pain with wee bit of cramping. Do you think this is a hormonal shift symptom. I have been eating more kale and dandilion tea. I work at an alternative med place and have been getting acupuncture for a couple of months. They seem to think that my treatments are causing the change. Any thoughts?

Thanks
